Zebrino Pianino

Zebrino Pianino is a secret-tier brainrot in Steal a Brainrot, the Roblox collection-and-trading game where every pet generates passive income and can be upgraded with mutations and traits. At base, Zebrino Pianino earns $7.3M/s and costs $1.2B from the in-game shop — those numbers are the floor, before any multiplier from mutations or trait stacking is applied.

For trade evaluation, divide the Robux value by your offer's value to get a clean ratio. The trade calculator does this automatically and applies trait amplifiers (Brilliant, Sniper, etc.) which add to base income additively rather than multiplicatively. See the methodology page for how the valuation algorithm actually computes these numbers, or the trade-valuation guide for a step-by-step walkthrough.
